Vertical dryer capable of drying more uniformly

Abstract

The vertical dryer comprises a drying box body, the drying box body is provided with at least two drying cavities, and the drying cavities are arranged in a layered mode in the upper side direction and the lower side direction; a feeding opening is formed in the upper side of the drying box body, a discharging opening is formed in the lower side of the drying box body, and a rotary discharging mechanism is arranged on the lower side of the drying cavity. The rotary discharging mechanism comprises a rotatable discharging pipe, the discharging pipe is transversely arranged, the discharging pipe is provided with a cavity and a transversely-extending axis, a material opening is formed in the discharging pipe, and the discharging pipe can rotate along the axis; and through the design of the discharging pipe of the rotary discharging mechanism, the discharging amount is more easily and accurately controlled, and the drying effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of drying devices, in particular to a vertical dryer with more uniform drying. Background technique [0002] In the production process of extruded pellets, micro pellets, pet food and other materials, low-temperature drying will be carried out on extruded pellets, micro pellets, pet food and other materials. The dryer mostly adopts a horizontal dryer, and the discharge is controlled by a flap. In practice, the discharge of the flap can only be estimated by the time and the opening angle of the flap, and the control of the discharge volume is not precise enough. Since the fluidity of the material will affect the discharge amount, the process of closing the door is always discharged, resulting in a different discharge amount each time and a large error that is difficult to quantify and control. If there are too many materials discharged, the drying time will be too short, and the materials will become moldy ...

AI Technical Summary

Problems solved by technology

If the gap is too large, it will cause material leakage, and some materials that have not reached the drying time will directly fall into the finished product, resulting in excessive moisture content or even mildew, which will affect the quality; if the gap is not enough, the materials will be crushed when the two flaps are closed.
